FILE JACKET.

Application filed February 8, 1924. Serial No. 691,456.

taining means formed in the sheet of which the jacket is made. I

A further object is to form the jacket with two series of sockets,oppositely located, for engagement by the ends of the resilient element,so that'the papers within maybe retained in compact form regardless ofthe thickness of the packet, if within the limits of the construct-ion.I

A still further object is to provide a device which shall include a rearelement aper tured at opposite ends and reinforced on the inner side, toprovide pockets for engagement by the resilient strip secured to onefree edge of the file jacket, at the back thereof. a

With the foregoing and other objects in View, the invention consists inthe novel construction described illustrated and claimed, it beingunderstood that modifications may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings, Figure 1 is a perspective view of the jacket, foldedFigure 2is a plan View of the open jacket; Figure 3 a plan View,showing-the other side of the open jacket; Figure 4 is a section on lineH of Figure 2; Figure 5 is a section on line 55 of Figure 3; Figure 6 isa fragmentary View of a modified construction; :Figure 7 is a section online 77 of Figure 6.

I provide a blank of tag board or the like,

including a central portion 10 adapted to constitute the front of thejacket, and including side flaps 11 and 12 each having a series of scorelines 13.

One edge 14 is folded over and incloses a resilient metallic strip 15,the folded-over portion being glued down or otherwise secured at 16, andthe ends being cut away at 17 to allow the strip to project as shown.

The flap 11 is provided with a series of slots 18 spaced from one edge,and a similar series 19 near the other edge. Any suitable number ofapertures is provided, and they may be designated by numerals, in orderthat corresponding apertures may be engaged by opposite ends of thestrip, without exercis ng particular care in securing the jacket. Theedge carrying the metallic strip is simply folded over, and portions 11and 12 are slightly creased on any of the score lines which provideproper adjustment. The spring is slightly bowed, the ends caused toengage corresponding sockets, and the spring then allowed to resumenormal position,thereby retaining the jacket securely.

In order to avoid contact between t-l'le'efnds of the spring and any ofthe papers, and to provide reinforcement, edge extension portions 11 ofthe flaps llare folded inwardly, and a suitable flexible reinforcementor-strip 20 is doubled and interposed'between each of portions 11 andthe flap. This strip 20 is provided with apertures registering with theapertures before mentioned in the jacket per se, and adjacent surfacesof the strip QOare free with reference to each other. but the surfacesadjacent to the" surfaces of elements 11 and 11 are glued to theelements last named This provides one long pocket with individualentrance openings represented by slots 18.

A long strip of material corresponding with that of the jacket comprisesmiddle portion secured to element 10, and end flaps 26, 27, to be foldedover the ends of the papers inclosed before the flapsll and 12 arefolded toward each other.

By means of this construction, I form the equivalent of a series ofpockets at the upper and lower edges of the jacket or envelope,

but avoid the use of separate securing devices for the individualpockets.

Another form includes a side flap provided with two series of openings,designated 36 and 37, near opposite ends of the flap, the aperturedportions being reinforced by a linen or other flexible strip such Z1338.

'In this form the edge of the jacket is not toward each other, resilientsecuring I'neans connectedwvith one edge portion and proectingtherefrom, an oppositely located portion of the sheet having parallelseries of 10 pockets for engagement by the resilient means, said pocketsincluding an inner Wall constituting a folded reinforcing strip, and anapertured Wall providing entrance openings, the folds of the inner andouter Walls 15 being on opposite sides of the pockets.

In testimony whereof I .afiiX my signature.

JOHN K. CASSEL.
